Stable Diffusion XL
Stable Diffusion XL generates images from text and supports optional LoRA weights.
- Text to image
- Image editing

Catalog preview for Stable Diffusion XL. Review your own result before publishing.
A starting point.
Build illustration or photo-style concepts with a specific subject, setting and light.
Before you publish.
Check anatomy, repeated objects and whether a LoRA overwhelms the intended composition.
Review the quote before running. A failed generation releases its reserved credits. Download the results you want to keep; stored media is retained for 30 days.
Settings and model questionsCheck the available settings and guidance when preparing your input.
Inputs and settings
Start with prompt and one image. Compare guidance_scale and num_inference_steps independently; add loras only when you need their effect.
For source-based changes, choose image-to-image with image_url. Inpainting also requires mask_url; both expose strength. Output format is JPEG or PNG.

Use Stable Diffusion XL through the API.
Start with this model ID for the endpoint featured on this page:
fast-sdxl
Input requirements belong to this model ID. Check a different mode’s schema separately when switching modes.
Available modes
- text-to-image ·
fast-sdxl - image-to-image (image-to-image) ·
fast-sdxl/image-to-image - image-to-image (inpainting) ·
fast-sdxl/inpainting
Check the current model schema for supported inputs and options. Other tasks may use different model IDs.
From quote to result.
Request a credit quote for your input and settings before submitting a generation. A sample output or the price of another model is not a quote for your request.
Follow the generation workflow, then poll the job for its status and result. The API and studio use the same balance.
